Summaries for Gm1-Gangliosidosis, Type Ii

OMIM : 53 GM1-gangliosidosis type II is an autosomal recessive lysosomal storage disease characterized by slowly progressive generalized neurodegeneration and mild skeletal changes, with onset between 7 months and 3 years of age. Unlike the severe infantile type I, type II is usually not associated with macular cherry-red spots or organomegaly. Within type II, those with somewhat earlier onset and earlier death are considered to have the 'late-infantile' form, whereas those with slightly later onset and survival into late childhood are referred to as having the 'juvenile' form (Caciotti et al., 2003). However, there is no strict age marker to distinguish between these 2 type II forms. GLB1 enzyme activity in type II ranges from approximately 1 to 4% of control values (Nishimoto et al., 1991; Yoshida et al., 1991). (230600)

MalaCards based summary : Gm1-Gangliosidosis, Type Ii, also known as gm1 gangliosidosis type 2, is related to gm1-gangliosidosis, type i and lysosomal storage disease, and has symptoms including ataxia, gait disturbance and optic atrophy. An important gene associated with Gm1-Gangliosidosis, Type Ii is GLB1 (Galactosidase Beta 1). The drugs Miglustat and 1-Deoxynojirimycin have been mentioned in the context of this disorder. Affiliated tissues include brain, spinal cord and bone.

UniProtKB/Swiss-Prot : 71 GM1-gangliosidosis 2: A gangliosidosis characterized by onset between ages 1 and 5. The main symptom is locomotor ataxia, ultimately leading to a state of decerebration with epileptic seizures. Patients do not display the skeletal changes associated with the infantile form, but they nonetheless excrete elevated amounts of beta-linked galactose-terminal oligosaccharides. Inheritance is autosomal recessive.

NIH Rare Diseases : 49 GM1 gangliosidosis is an inheritedlysosomal storage disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord. The condition may be classified into three major types based on the general age that signs and symptoms first appear: classic infantile (type 1); juvenile (type 2); and adult onset or chronic (type 3). Although the types differ in severity, their features may overlap significantly. GM1 gangliosidosis is caused by mutations in the GLB1 gene and is inherited in an autosomal recessive manner. Treatment is currently symptomatic and supportive. Last updated: 11/17/2015
